FLOOR-HINGE.

SPECIFICATION 'forming pan-.I of Letter; Patent No. 700,221, dated May2o, 1 902. Application filed March 27, 190].. Serial No. 53,029. (Nomodel.) d v T0 all whom, it may concern):

Chicago, county of`Cook, and State of Illinois,

have invented certain new and usefulIm-f provements in Floor -Hinges, ofwhich the pintle, showing one element of my improvel following is aspecification.

My invention relates to hinges `for doors and similar swingingstructures,and has been designed more especiallyas an irnprovement'inthat class of hinges known as floor-hinges, in which the doorv or otherswinging member is supported in operative position throughl the agencyof a pair of vertically-disposed pivot-bolts or pintles, one of whichhas a rotatable bearing in the floor or sill under the base or loweredgeof 'the door and the other of which has a similar bearing in thedoor frame or casing above the top or upper edge of the door, saidpintles both being disposed in the vertical axis about which the doorswings and having their inner ends IiXedlyV secured in the lowerY andupper edges ot the door or invsuitable keepers attached-thereto.

Hinges ofthe above-described class havethem by a weight, wedge-block,hook, ori

similar independent device acting on the outer or open end ot' the door.

The object of my present invention is to provide a simpleandeasily-operated device directly connected and associated with the hingeitself, whereby the door may be readily locked in Vits open positionl oneither side of its intermediate or closed position and may be asVreadily unlocked, the locking and-unlocking'being effected,preferably,`by a pushA of the foot on the part of the operator; and to'thisend my invention consists in an interlocking device associated withthe pintle of the hinge and operating in the manner hereinafterdescribed and claimed.

My invention in its preferred form isillustrated in the accompanyingdrawings, in which- A Figure 1 is a top'plan View of the top plate orcover of the casing containing -the hingement applied thereto. Fig. 2 isa similar view in bottom plan; Fig. -3 is acentral vertical'sectionthrough the casing, showing the hinge-pintle and its associatedmechanism lplate or cover for the casing, such cover being preferablyformed, as shown, in two parts 9 and 10.

bolt 11, the npper'end ofwhich passes through andis journaledin a hole12, formed through a boss 13 on thepupperf'face of the member 9. Thatportion' of 'the pintle lying above ,the boss 13 is squared' oriiattened on opposite sides and engages acoi'respondingly-shaped hole orsocket formed in a keeper 14, secured to the lower edge of-the door 7. Y

At 15, 16, and 17 I have shown in Fig. 3 a closing-spring andintermediate cooperating devices between the latter and the pintle; butas these latter form no part of my present invention they need not bemore particularly described.

Referring now more particularly to the device forming thesubject-mattenot my present improvement, 18 indicates vone niember of mylocking device, Whichin the' form illustrated consists offahorizontally-disposed bolt or pin rectangular in `cross-sectionandpassing transversely through-the body of the pintle 11 just below theplate or covenSand projecting a certain distance on either side thereof.19 indicates the other cooperating member of the lock, which in the formshown consists of a slidable plate held between parallel guides 20ronthe under face of the member 10 In the lbottom of--the casing isjournaled a vertically-,disposed pintle or pivot- IOO and having formedin that side thereof which lies nearest the pintle 11 a slot or recess21 of a size to receive either end of the pin 18. This slotted plate 19is slidably secured on the under face of the plate 10 by means of ascrewbolt 22 passing through a slot 23 in said plate and engaging aslide 24, located over the slot 23, the said slide being preferablyprovided with an upturned end or projection 25, which latter mayconveniently be engaged by the foot of the operator to cause the lockingmember 19, through vthe described connections, to

engage and disengage the pin 18, as desired.

26 and 27 indicate suitable holes formed through the plates 9 and 10,respectively, whereby said plates may be secured, as by screws, in thehorizontal flange of the casing 5.

I n Fig. 4 I have shown my invention applied to the simplest form offloor-hinge, the latter comprising merely a vertical pintle 11, restingin a boss 28, formed on the base of the casing 5, and having its upperend journaled in a boss 13, formed on the plate 9, and entering asuitable socket in the lower edge of the door 7.

The elements of my invention as applied to a simple form of hinge, suchas that last described, are identical in construction, application, andmode ot operation to the same, as shown in Figs. 1 to 3, inclusive, andare therefore indicated by the same reference numerals.

The operation of my invention will be readily understood from theforegoing description, but m ay briefly be described as follows: NVhenthe dooris in its closed position, the spring 15 is inactive and theplane of the door is at right angles to that indicated in Figs. 3 and 4.At such a time it will be evident that the pin 18 occupies a positionalso at right angles to the position shown in Figs. 3 and 4, whichposition is at right angles to the longitudinal axis of the slidinglocking member 19. WVhen now the door is open to the extent of ninetydegrees, the pin 18 will thereby be brought into longitudinal alinementwith the slot 21 in the plate 19, and thereupon the operator by pushinginwardly with his foot upon the projection 25 will force the plate 19into locking engagement with the adjacent end of the pin 18, asindicated in Fig. 1, and the door will thereby be securely held in itsopen position. A simple reverse of this operation separates theinterlocking parts 18 and 19 and permits the door to be closed by itsspring 15, as in Fig. 3, or by manual means,.as in Fig. 4.

It will be obvious from the foregoing description that the improvementconstituting my present invention is not limited in its application toany particular form of floor-hinge, it being essential only that thehinge shall comprise as one of its elements a main pintle or pivot boltor similar element.

The form of hinge-containing casing shown and described is by no meansessential, and so far as the application of my invention is concernedthe casing might be entirely omitted, the hinge being set in a mortiseor recess in the floor or sill and the sliding element 19, withitsoperating parts, being disposed in another groove or mortise adjacentthereto. Preferably, however, a containing casing for thelock mechanismwill be employed,or at least a metallic plate, such as 8, made eitherintegral or in parts, as shown, in order to afford a secure upperbearing for the hingepintle and also an adequate support for thecoperating locking member 19.` I wish it also to be understood that myinvention is not limited to a device in which a transverse pin fixed inthe hinge-pintle is engaged by a slidable slotted coperating lockingmember. It will be obvious that any number of lateral projections formedintegral with or otherwise secured on the pintle would be the equivalentof the transverse pin 18, the greater the number of these projectionsemployed the greater being the n umber of positions at which the doormay be held open. In practice, however, it is usually desirable tomaintain the door in an open position on either side of its closedposition at right angles to the latter. For that purpose the pin 18,projecting on diametrically opposite sides of the pintle, is obviouslysuflicient and aliords a simple and inexpensive means for effecting thedesired result. A construction in which the movable element was carriedby the pintle and the stationary element supported by the casing-coverwould be the obvious converse of what I have shown and described andwould be within the spirit and intended scope of my invention. It isalso obvious that the slotted character of the sliding member 19 is notessential, since a simple sliding bar engaging the pin 18 on the properside thereof to resist the closing tendency of the spring might beemployed in place thereof. The essential features of my invention arecomprised in the combination With the hinge-pintle or similar element ofa floor-hinge, of a pair of interlocking elements in associationtherewith, one of the elements being carried by or formed on the pintleand the other being disposed adjacent thereto and one of the elementsbeing movable into and out of locking engagement with the other.

I claim- 1. In a floor rotatable hinge, the combination with thehinge-pintle of a pair of interlocking elements associated therewith,one of which elements is fixed with respect to the pintle and the otherof which is disposed adjacent thereto and projects above the floor andis adapted to be moved by the foot of the operator into and out oflocking engagement with the xed element whereby the door is maintainedopen or permitted to close.

2. In a floor rotatable hinge, the combination with the hinge-pintle andits containing casing of a xed lateral projection carried by said pintleand a sliding member carried by tho top plate oi' the casin g adapted tobe IOO IIS

Igo

moved into and `ont oflateral engagement with said projection tomaintain lliedoor `open or permit it to close.

3. In a floor rotatable hinge, the combina-l tion with the hinge-pintleot' a series of fixed lateralprojections carried by said pintle, and asliding member disposed adjacent the pintle and adapted to be moved intoand out of lateral engagement with one of said projec-l tions, in themanner and for the purpose described. Y 4. In a'loor-hinge, thecombination with .the hinge-pintle and its containing casing of ja pinextending transversely through l'said pintle immediately below;rtopplate o`f the 5,l i casing and projecting laterally therefrom, a lslotted-plate slidably secured toxthe under face of the top plateand'movable intofand out of engagement with thejprojecting ends 'v e of saidpin, and means disposed on top of 2o said top plate, connected withsaidvslotted plate, adapted to be actuated by thevfoot of the operator.
